Jim: Hi, Bob!

Bob: Hello, Jim! What are you doing now?

Jim: I am writing an email on the computer. What about you?

Bob: I am writing a postcard. I want to send it to Steven. He is in Canada now.

Jim: May I see your postcard?

Bob: Sure! Here you are.

Jim: It is very beautiful. It has a picture of the Great Wall on it.

Bob: Steven likes the Great Wall very much.

Jim: Oh, I want to buy a postcard for my friend Betty. She likes the Palace Museum. How much is your postcard?

Bob: It is three yuan. Let's go to the shop to buy some postcards. After we write them, we can send them at the post office.

Jim: Okay. Let's go!
